CSNOMA: Carrier Sense Non-Orthogonal Multiple Access [PDF]
Sensors, 2020 In this paper, we investigate the possibility of the cross-layer design of a distributed random access scheme with considering physical (PHY) and multiple access control (MAC) layers, which utilizes the interference cancellation technique. In this regard,

Rate Compatible Modulation for Non-Orthogonal Multiple Access [PDF]
IEEE Access, 2020 We propose a new Non-Orthogonal Multiple Access (NOMA) coding scheme based on the use of a Rate Compatible Modulation (RCM) encoder for each user. By properly designing the encoders and taking advantage of the additive nature of the Multiple Access ...

Non orthogonal multiple access with wind energy harvesting
Alexandria Engineering Journal, 2023 In this paper, we derive the performance of wireless communications using wind energy harvesting. We study the single-user and multi-user scenarios using Non Orthogonal and Orthogonal Multiple Access (NOMA and OMA).

Trellis-Coded Non-Orthogonal Multiple Access [PDF]
IEEE Wireless Communications Letters, 2020 In this letter, we propose a trellis-coded nonorthogonal multiple access (NOMA) scheme. The signals for different users are produced by trellis coded modulation (TCM) and then superimposed on different power levels. By interpreting the encoding process via the tensor product of trellises, we introduce a joint detection method based on the Viterbi ...

Non-Orthogonal Frequency Division Multiple Access [PDF]
2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring), 2020 This paper proposes a frequency-domain multiple user access scheme termed non-orthogonal frequency division multiple access (NoFDMA), which maintains the same data rate per user while allowing more users to access via non-orthogonal user overlapping in a given spectral band.
